Item 1. Description of Business.

Organization

         Presidential Associates I Limited Partnership (the "Partnership") was
organized as a Maryland limited partnership under the Maryland Revised Uniform
Limited Partnership Act on July 20, 1983, for the purpose of investing in
Presidential Towers Ltd. (the "Operating Partnership"), an Illinois limited
partnership organized for the purpose of building, owning and operating a
residential apartment complex in downtown Chicago, Illinois (the "Project").

         The general partners of the Partnership are Winthrop Financial Co.,
Inc., a Massachusetts corporation ("Winthrop Financial"), and Linnaeus-Phoenix
Associates Limited Partnership ("Linnaeus-Phoenix"). Winthrop Financial is the
Partnership's managing general partner. Collectively, Winthrop Financial and
Linnaeus-Phoenix are referred to herein as the "General Partners." Winthrop
Financial is a wholly-owned subsidiary of First Winthrop Corporation which is
wholly owned by Winthrop Financial Associates, A Limited Partnership ("WFA").
See "Employees" below.

         The only business of the Partnership is investing as a limited partner
in the Operating Partnership. As of the date hereof, the general partners of the
Operating Partnership are (i) McHugh Levin Associates Venture ("McHugh Levin"),
an Illinois limited partnership whose general partners are James P. McHugh and
Daniel E. Levin, (ii) Madison-Canal Company, an Illinois limited partnership
whose general partner is Daniel J. Shannon and (iii) TKI Presidential Partners.

         As of the date hereof, the Partnership holds a 19.998% limited
partnership interest in the Operating Partnership. In exchange for this interest
the Partnership made a capital contribution of $33,172,524 to the Operating
Partnership. See "Restructuring of Operating Partnership."

Development

         The Partnership was initially capitalized with contributions totaling
$300 from the General Partners. In September 1983, the Partnership completed a
private offering of 590 units of limited partnership interest (the "Units")
pursuant to Regulation D under the Securities Act of 1933. The Partnership
raised $59,000,000 in capital contributions from 545 investor limited partners
(the "Limited Partners"). Of the $59,000,000 raised, $697,380 was received upon
the Limited Partners' admission to the Partnership, and the balance was paid in
installments pursuant to the terms of promissory notes (the "Investor Notes")
delivered to the Partnership by the Limited Partners. The last installment was
due on January 15, 1990. As of March 1, 2000, $56,094 of this installment
remains uncollected.

         The General Partners and the general partners of the Operating
Partnership projected that reserves and deficit loans would be sufficient to
fund operations until the Project could achieve


<PAGE>


break-even operations. However, due to lower than projected revenues and higher
than projected real estate taxes, the Project's cash flow deficit was
significantly higher than anticipated, and thus the reserves were depleted
sooner than anticipated.

Restructuring of Operating Partnership

         After failing to meet its mortgage obligations, the mortgage loan on
the Project was assigned by the lender to the Department of Housing and Urban
Development ("HUD") which had insured the mortgage. The Operating Partnership
and HUD entered into a written tentative Restructuring Agreement (the
"Restructuring Agreement") in December 1991. The Restructuring Agreement, which
was implemented on April 18, 1995 and was approved by a majority in interest of
the limited partners of the Partnership, provided for the split of the then
existing mortgage note into two new mortgage notes. This was designed to afford
the Project achievable debt service obligations under the Restructuring
Agreement. Both new mortgage notes mature on the same date as the original
mortgage loan, September 1, 2028. HUD will, however, have the right to
accelerate the obligations evidenced by the notes at any time after June 1,
2015. See "Refinancing of HUD Loan" below.

         Each of the notes is prepayable in whole or in part at any time without
penalty. The first mortgage note, in the original principal amount of
$127,000,000, bears interest at an annual rate of 8.1%. All accrued and unpaid
interest will be compounded annually at the rate of 8.1%. The first mortgage
note consists of two tiers. The first tier, in the principal amount of
$71,000,000, is to be repaid through level monthly payments which amortizes the
debt over the remaining loan term. A service charge payable to HUD in the amount
of 0.5% per annum of the then outstanding principal mortgage balance will be
payable monthly. The secondary tier note is in the amount of $56,000,000. The
secondary tier requires semi-annual payments of principal and interest in an
amount equal to 80% of the Project's net cash flow; provided, however, that
commencing on the tenth anniversary of the closing (June 1, 2005), the
semi-annual payments will be in an amount equal to the greater of (i) 80% of the
Project's net cash flow or (ii) a fixed minimum payment of $164,025 that shall
increase each year between the eleventh year and twentieth year after closing.
The Operating Partnership made payments aggregating $1,300,000 on account of the
secondary tier during 1998. The annual HUD 0.5% service charge accrues on the
then outstanding principal amount of the second tier and will be due only upon
prepayment in full of the first mortgage note or maturity of the first mortgage
note. In addition, the Operating Partnership is obligated to reduce the
secondary tier's principal by a total of $10,000,000 over a six year period
expiring June 1, 2001. This $10,000,000 obligation has been funded as described
below.

         The original principal amount of the second mortgage note was
$63,001,421. The second mortgage note bears no interest and is payable from
available proceeds from a sale or refinancing of the Project. While the new
second mortgage note bears no interest, after payment in full of the principal
amount of the second mortgage note from the proceeds of a sale or refinancing of
the Project, 40% of all additional sale or refinancing proceeds shall be paid to
HUD until HUD shall have received $20,000,000 in excess of the principal amount
of the second mortgage note. HUD has the right to call this second note at any
time on or after June 1, 2015. The Restructuring



                                       3
<PAGE>


Agreement also required the Operating Partnership to establish a deficit escrow
account of $3,000,000 over a six year period from sources other than the
operating revenues of the Project to provide additional collateral security for
the mortgages. The two capital requirements described above (the $10,000,000
reduction to the first mortgage note's second tier and the $3,000,000 deficit
escrow account) necessitated raising $13,000,000 of new equity (available over
six years, as required).

         In order to implement the Restructuring Agreement and raise the
$13,000,000 of new equity, a third party investor, TKI Presidential Partners
("TKI"), was admitted to the Operating Partnership as a general partner. TKI
agreed to contribute $14,000,000 over a six year period (as required by the
Restructuring Agreement with HUD) in exchange for a 79% general partnership
interest in the Operating Partnership, 79% of all future distributions by the
Operating Partnership of operating cash flow, a preferential return of its
capital contribution from the proceeds of a sale or refinancing, 79% of all
additional proceeds of a sale or refinancing, 100% of all future tax losses of
the Operating Partnership and effective control, through rights to approve or
initiate certain actions, over all major business decisions affecting the
Operating Partnership. As a result of TKI's investment, the Partnership's
interest in the Operating Partnership was reduced from a 94.99% limited
partnership interest to a 19.998% limited partnership interest and certain
control rights over major business decisions of the Operating Partnership were
transferred to TKI. As of December 31, 2000, TKI had funded $12,320.000 of its
$14,000,000 obligation. Pursuant to the terms of the Partnership Agreement of
the Operating Partnership, the Partnership is entitled to receive a distribution
from the Operating Partnership to reimburse it for its administrative expenses
and professional fees up to an annual maximum of $30,000. In addition, the
Operating Partnership made distributions to the Partnership during 1998, 1999
and 2000 of $327,592, $434,876, and $225,210 respectively. However, due to TKI
being entitled to a priority return, there can be no assurance that the
Operating Partnership will be able to make additional distributions to the
Partnership, if at all, until the property is sold. However, due to the
preferred return to TKI and HUD, it is possible that a sale will not generate
sufficient funds to permit a distribution to the Partnership. Accordingly, it is
anticipated that limited partners will not receive a return of their original
investment in the Partnership.

Refinancing of HUD Note

         On January 10, 2001, the Operating Partnership purchased the two
mortgage notes from HUD by refinancing the Project with a new first mortgage
loan secured by the Project with a third party lender. The new mortgage requires
payments of interest only at a rate of 6.55% per annum and matures on February
1, 2011. The Operating Partnership will recognize an extraordinary gain for
financial reporting purposes of $57,000,000. As a result of the refinancing, the
regulatory agreements with HUD and the Restructuring Agreement were terminated.

Employees

         The Partnership has no employees. On December 16, 1997, Winthrop
Financial and certain of its affiliates entered into a Services Agreement with
Coordinated Services of Valdosta,



                                       4
<PAGE>


LLC ("Coordinated Services") pursuant to which Coordinated Services was retained
to provide asset management and investor services to the Partnership and certain
affiliated partnerships. As a result of this agreement, Coordinated Services has
the right to direct the day to day affairs of the Partnership, including,
without limitation, reviewing and analyzing potential sale, refinancing or
restructuring proposals by the Operating Partnership, preparation of all
Partnership reports, maintaining Partnership records and maintaining bank
accounts of the Partnership. Coordinated Services is not permitted, however,
without the consent of Winthrop Financial, or as otherwise required under the
terms of the Partnership's Agreement of Limited Partnership (the "Partnership
Agreement") to, among other things, cause the Partnership to consent to a sale
of an asset or cause the Partnership to file for bankruptcy. As compensation for
providing these services, Winthrop Financial and its affiliates assigned to
Coordinated Services all of their right to receive fees from the Partnership as
provided in the Partnership Agreement. See "Item 12, Certain Relationships and
Related Transactions."

Item 2. Description of Properties.

         The Partnership has no properties other than its interest in the
Operating Partnership. For a description of the properties of the Operating
Partnership, see Item 1, Description of Business.

Item 3. Legal Proceedings.

         To the best of the Partnership's knowledge, there is no material
pending legal proceedings to which it is a party.

Item 4. Submission of Matters to a Vote of Security Holders.

         No matter was submitted to a vote of security holders during the period
covered by this report.

                                     PART II

Item 5. Market for the Partnership's Common Stock and Related Security Holder
        Matters.

         The Partnership is a limited partnership and thus has no common stock.
There is no established public trading market for the Units of limited
partnership interest in the Partnership. Trading in Units is sporadic and occurs
solely through private transactions.

         As of March 1, 2001, there were approximately 580 holders of 590
outstanding Units.

         The Partnership Agreement requires that Cash Flow (as defined therein)
be distributed to the partners in specified proportions at reasonable intervals
during the fiscal year and in any event no later than 60 days after the close of
each fiscal year. There are no restrictions on the Partnership's present or
future ability to make distributions of cash flow. For the years ended December
31, 1999 and 2000, the Partnership made distributions to its limited partners of
approximately $321,750 ($545.34 per Unit) and $346,500 (587.29 per Unit)
respectively, and $1,625 and $ 1,750 to each of the General Partner and the
special limited partner. See Item 6 "Management's Discussion and Analysis or
Plan of Operation" for the Partnership's ability to make distributions in the
future.

         Over the past few years many companies have begun making "mini-tenders"
(offers to purchase an aggregate of less than 5% of the total outstanding units)
for limited partnership interests in the Partnership. Pursuant to the rules of
the Securities and Exchange Commission, when a tender offer is commenced for
Units the Partnership is required to provide limited partners with a statement
setting forth whether it believes limited partners should tender or whether it
is remaining neutral with respect to the offer. Unfortunately, the rules of the
Securities and Exchange Commission do not require that the bidders in certain
tender offers provide the Partnership with a copy of their offer. As a result,
the General Partners often do not become aware of such offers until shortly
before they are scheduled to expire or even after they have expired.
Accordingly, the General Partners do not have sufficient time to advise you of
its position on the tender. In this regard, please be advised that pursuant to
the discretionary right granted to the General Partners of your partnership in
the Partnership Agreement to reject any transfers of units, the General Partners
will not permit the transfer of any Unit in connection with a tender offer
unless: (i) the Partnership is provided with a copy of the bidder's offering
materials, including amendments thereto, simultaneously with their distribution
to the limited partners; (ii) the offer provides for withdrawal rights at any
time prior to the expiration date of the offer and, if payment is not made by
the bidder within 60 days of the date of the offer, after such 60 day period;
and (iii) the offer must be open for at least 20 business days and, if a
material change is made to the offer, for at least 10 business days following
such change.

Item 6. Management's Discussion and Analysis or Plan of Operation.

         The matters discussed in this Form 10-KSB contain certain
forward-looking statements and involve risks and uncertainties (including
changing market conditions, competitive and regulatory matters, etc.) detailed
in the disclosure contained in this Form 10-KSB and the other filings with the
Securities and Exchange Commission made by the Partnership from time to time.
The discussion of the Partnership's business and results of operations,
including forward-looking statements pertaining to such matters, does not take
into account the effects of any changes to the Partnership's business and
results of operation. Accordingly, actual results could differ materially from
those projected in the forward-looking statements as a result of a number of
factors, including those identified herein.

Liquidity and Capital Resources

         The Partnership's primary source of liquidity is distributions from the
Operating Partnership. As a result of the restructuring, the Partnership is
entitled to receive a distribution from the Operating Partnership to reimburse
it for its administrative expenses and professional fees up to an annual maximum
of $30,000 to cover these costs. During 2000, the Partnership received
distributions totaling $225,210 from the Operating Partnership as compared to
$434,876 in 1999. Due to TKI being entitled to a priority return from the
Operating Partnership, there can be no assurance that the Operating Partnership
will be able to continue to make distributions to the Partnership until the
property is sold. Furthermore, due to the preferred return to TKI and HUD, it is
possible that a sale will not generate sufficient funds to permit a distribution
to the Partnership. Accordingly, it is anticipated that limited partners will
not receive a return of their original investment in the Partnership. See "Item
1, Business-Restructuring of Operating Partnership."

         The Partnership's liquidity, based on its cash and cash equivalents,
was $268,773 at December 31, 2000 as compared to $433,334 at December 31, 1999.
This decrease was due to $350,000 of distributions to partners which more than
offset $181,328 of cash provided by operating activities and $4,111 of
contributions from investor limited partners.

Results of Operations

         The Partnership's net income for the year ended December 31, 2000 was
$181,328 as compared to $394,503 for the year ended December 31, 1999. The
decrease in net income is the result of a decrease in distributions from the
Operating Partnership and an increase in expenses which was partially offset by
a slight increase in interest income. Distributions from the Operating
Partnership decreased to $225,210 in 2000 from $434,876 in 1999. Interest income
increased slightly due to higher cash balances. Operating expenses increased
from $49,503 in 1999 to $58,191 in 2000.

         As discussed above, future operation of the Partnership are subject to
the Operating Partnership's ability to make distributions to the Partnership.
Expenses are expected to remain relatively constant for future periods.

                                       7
<PAGE>

         The General Partners believe that the inflation rate did not materially
affect the business or operating results of the Partnership during the last
three years; however, as discussed in Item 1 above, general economic conditions
have had a substantial effect on the operations of the Operating Partnership
since 1988. The residential market in Chicago is expected to continue to be
competitive for the foreseeable future.

                          INDEPENDENT AUDITORS' REPORT



To the Partners
Presidential Associates I Limited Partnership

         We have audited the accompanying balance sheets of Presidential
Associates I Limited Partnership as of December 31, 2000 and 1999, and the
related statements of income, partners' equity (deficit) and cash flows for the
years then ended. These financial statements are the responsibility of the
partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Presidential
Associates I Limited Partnership as of December 31, 2000 and 1999, and the
results of its operations, changes in partners' equity (deficit) and its cash
flows for the years then ended, in conformity with generally accepted accounting
principles.

                    NOTES TO FINANCIAL STATEMENTS - CONTINUED

                           December 31, 2000 and 1999

NOTE A - ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The partnership was organized under laws of the State of Maryland on July 1,
    1983 to acquire a limited partnership interest in Presidential Towers, Ltd.
    (the "operating partnership").

    Use of Estimates

    The preparation of financial statements in conformity with generally
    accepted accounting principles requires management to make estimates and
    assumptions that affect the reported amounts of assets and liabilities and
    disclosure of contingent assets and liabilities at the date of the financial
    statements and the reported amounts of revenue and expenses during the
    reporting period. Actual results could differ from those estimates.

    Investment in the Operating Partnership

    The investment in the operating partnership is reported using the equity
    method of accounting, under which the initial investment is recorded at
    cost, increased or decreased by the partnership's share of income or
    losses, and decreased by distributions. The investment cannot be reduced
    below zero.

    Federal and State Income Taxes

    No provision or benefit for income taxes has been included in these
    financial statements since taxable income or loss passes through to, and is
    reportable by, the partners individually.

    Cash Equivalents

    For the purposes of the statements of cash flows, the partnership considers
    all highly liquid financial instruments, which consist of a money market
    account and amounts invested under a repurchase agreement, purchased with
    maturities of three months or less, to be cash equivalents. The carrying
    amount approximates fair value because of the short maturity of these
    instruments.

NOTE B - INVESTMENT IN OPERATING PARTNERSHIP

     The partnership held a 94.99% interest in the operating partnership which
     constructed, owns and operates four 49-story residential and commercial
     towers in Chicago, Illinois. During 1995, the partnership agreed to the
     restructuring of the operating partnership which included the admission of
     an additional general partner and an amendment to the operating
     partnership's partnership agreement. The amendment resulted in the
     partnership's interest in the operating partnership being reduced to
     19.998%. Further, all losses from the operating partnership are allocated
     to the new general partner.

     On January 10, 2001, the operating partnership refinanced its existing
     mortgages into a first mortgage note which will result in an extraordinary
     gain of approximately $57 million on extinguishment of debt in 2001.

     The following is a summary of the financial position of the operating
     partnership at December 31, 2000 and 1999, and a summary of its results of
     operations for each of the two years in the period ended December 31, 2000,
     prepared in conformity with generally accepted accounting principles.

    The unrecognized portion of cumulative losses will be offset against the
    partnership's share of future income from Presidential Towers, Ltd. The
    cumulative unrecognized loss at December 31, 2000 and 1999 is $87,205,197
    and $87,430,407, respectively.

NOTE C - RECONCILIATION OF NET INCOME

    The partnership's income for tax purposes for 1999 is the same as income
    for financial statement purposes.

    The partnership's income for tax purposes for 2000 is greater than its
    income for financial statement purposes by $299,970 to reflect distributions
    accrued from the operating partnership for tax purposes which are not
    recorded for financial statement purposes.

    In addition, there is no difference between buildings and improvements as
    recorded for tax purposes and financial statement purposes by the operating
    partnership for 2000 and 1999.

NOTE C - RECONCILIATION OF NET INCOME (Continued)

    The difference between the investment in the operating partnership for tax
    purposes and financial statement purposes is due to the difference in the
    losses not recognized under the equity method of accounting which are
    recorded for income tax purposes. The balance of the investment in the
    operating partnership for tax purposes is $(83,990,156) at December 31, 2000
